The German fourth seed will face 11th seed Kyle Edmund in the last eight.

The 21-year-old Zverev was ruthless as he took the first set in just 29 minutes, although his 19-year-old opponent showed more fight in the second.

Zverev has been suffering from a cold but ratcheted up the pressure to grab the all-important break of serve in the ninth game before closing out the match against de Minaur, who this week replaced Nick Kyrgios as Australia’s top-ranked player.
